What is BS EN 4804 - 4 holes aerospace swivel flanges about?
The flange coupling is a driving coupling placed between rotating shafts. These shafts comprise a flange fixed on each shaft end, and are held and bolted together using a ring of bolts that complete the drive. These couplings are designed to seal two tube ends in a flush manner. 
BS EN 4804 specifies the characteristics of swivel flanges, 4 holes, for flange couplings in nickel alloy for inch series aerospace applications.
BS EN 4804 determines the nominal pressure to be up to 21 000 kPa, depending on associated seal, tube material, tube diameter, and tube wall thickness in the assembly which can be seen in EN 4814.
Who is BS EN 4804 - 4 holes aerospace swivel flanges for?
BS EN 4804 for 4 holes swivel flanges for aerospace flange coupling in nickel alloy is useful for:
- Manufacturers of aircraft 
- Manufacturers, and suppliers of aerospace components 
- Product design engineers 
- The military sector 
- Quality control teams 
Why should you use BS EN 4804 - 4 holes aerospace swivel flanges?
BS EN 4804 provides you with the guidelines for the required configuration, design, dimensions, tolerance, and masses to ensure reliable, and accurate alignment of bolt holes with the swivel flange in nickel alloy.
BS EN 4804 guidelines enable you to design, and manufacture quality swivel flange with 4 fastening holes, in nickel alloy that contribute to aviation safety, and quality.
